IMPROVEMENT m PAPER BOXES.

Specification forming part of Letters Patent No. 591,276, dated May 29,1877; application filed April 23, 1877.

To all whom it may concern:

Be it known that 1, MICHAEL Bncxns, of Wallingford, in the county of NewHaven and State of Connecticut, have invented a new and Improved Box forExplosive Caps, of which the following is a specification:

Figure l is a perspective view of my invention, showing four of theimproved boxes placed one upon the other. Fig. 2 is a vertical sectionthrough two of the improved boxes, standing the one upon the other. Fig.3 is a plan or face view of the blank from which the cover of the box ismade; Fig. 4, a plan or face view of the blank from which the body ofthe box is made.

Similar letters of reference indicate corresponding parts in all thefigures.

The object of this invention is to produce an inexpensive box forholding small paper explosive caps and other explosive caps safelyduring transportation and storage.

The invention consists, principally, in making the body of the box of apaper or paste board blank, which is merely bent up into box form, butnot secured at the corners, and in the combination of such a paper orpasteboard box with a metallic cover similarly made, the sides of thecover reaching down to the bottom of the box.

The invention also consists in forming recesses in the lower edges ofthe cover, all as hereinafter more fully described.

A in the drawing represents the body of the box. It is made of paper orpasteboard, or equivalent flexible material, from a blank substantiallylike that shown in Fig. 4. The flaps of this blank are turned up to formthe sides of the box, but remain unconnected at the corners. Thisconstruction, which, in connection with the metallic cover B, rendersthe box sufliciently perfect, has the additional ad vantage that thedisconnected sides, in their tendency to resume the level with thebottom, press with sufficient firmness against the cover as toretain'the box and cover properly united. The box is also very much lessexpensive than if its sides were united at the corners, as in the shapeshown the blank can be out from a sheet and its flaps bent up at onesingle operation.

The cap or cover B is made of metal, or equivalent rigid or stiffmaterial, from a blank substantially like that shown in Fig. 3. Theflaps of this blank are-also turned up to form the sides of the cover,and remain also disconnected at the corners. The nature of the materialfrom which the cover is made causes it to retain the shape imparted toit. The lower edges of the cover have recesses 00 a cut into it, to givea hold to the fingers in withdrawing the cover from the box. The sidesof the cover extend down as far as the bottom of the box A, and thus thebox is entirely surrounded with metal except at' the bottom, whichremains flexible. This is a peculiar advantage, as in packing theseboxes, after they have been filled with the explosive material, they areplaced one upon the other, as in Figs. 1 and 2, which causes theflexible bottom of exery box to bear upon the hard cover of the box nextbelow, and to serve as a yielding cushion, which will prevent anyappreciable amount of concussion between the boxes, and consequentexplosion of their contents.

If it were not for the notches or recesses a in the sides of the cover,that otherwise completely overhang the body of the box, the removal ofthe cover would be exceedingly difficult.

I claim as my invention- 1. The combination of the flexible pasteboardbox A with the rigid metallic cover B, whose sides extend down as far asthe bottom of the box, so that the closed box will have a flexiblebottom and rigid top and sides, substantially as herein shown anddescribed.

2. The combination of the flexible pasteboard box A with the rigidmetallic cover B, the sides of said cover extending down to the bottomof the box, and being provided with the notches or recesses a a at theirlower edges, substantially as herein shown and described.

MICHAEL BACKES.
